Jenny is a student at the Constance Billard School for Girls, a small, elite, all-girls school located on the Upper East Side, which Serena van der Woodsen and Blair Waldorf also attend.
Blair informs Rufus that Jenny has been skipping school and he confronts her.
Blair attempts to sabotage Jenny’s work in the show but Jenny improvises, proposing that Serena and the socialites walk the runway.
In an effort to ruin Serena, Blair switches the final dress with one that Jenny made, drawing Eleanor's ire.
Despite this, the dress is a huge hit with the audience and the fashion show is a big success.
In the Gossip Girl prequel It Had To Be You, Jenny is noted for having a rather flat chest until she begins taking breast enlargement supplements, which turns out are the cause of her double D cup size.
